Answer:
52, 60, 68, 76..
Step-by-step explanation:

1.25 x 5.20 = 6.50 final amount due.
The easiest way to do this is to plot the points. I used the pythagorean theorem for this one, too. Add the side lengths to get the perimeter: 5 + 5 + 5 + 3 + √40 = 24.32455532 units or just 24 units.
I believe that a flat surface continuing in all directions is called a plane.
